Fluorite

Fluorite is a colourful, glassy mineral found in Starsand Island's ore deposits, typically recognised by its vivid purple, green, or blue hues. In the real world, fluorite is prized both as an ornamental stone and as an industrial flux mineral used in metalworking. On the island, it appears as a mid-to-late game resource in deeper or more remote mining areas, rewarding players who push further into the terrain.

Fluorite is used in advanced crafting recipes that require unusual mineral components, likely contributing to high-tier tools, decorative items, or alchemical preparations. Its relative rarity compared to basic ores makes it a valuable commodity, and players who explore the island's mining locations thoroughly will want to set aside a stockpile for when fluorite-requiring recipes become available.
